So I recently paid to have a non abrasive chemical spayed at the office to kill fireants and the like. Worked great and they Haven't come back yet but now we have sugar ants and there every where. The question is this. Do big ants eat the small ants?, and which is worse in the long run?

straight lemon juice put it in a spray bottle and spray your window sill and door ways . carpenter ants are the bad one.they love termite , but when they get done eating them they will start eating the wood in your house.
